Abstract

The utility model relates to a machine tool for processing a lower sealing head of a cylinder. The utility model is composed of a bed piece, upright posts, an unloading and dropping device, a hydraulic ram, a compressing device, a main shaft, a rotary transmission device, a tension device for a positioning tyre, etc. The utility model adopts the structure that the hydraulic ram, the compressing device, the unloading and dropping device, the tension device for a positioning tyre and the main shaft are jointly positioned in the same axis arrangement, and both sides which are perpendicular to the axis are respectively provided with an edge narrowing hob device and an edge trimming hob device. Therefore, the processing verticality of a port of a workpiece of the lower sealing head can be ensured, processing time is shortened, production efficiency is enhanced, and labor force and ground are saved.

Description

The machining tool of steel cylinder low head

The utility model relates to the field of machining equipment, particularly the machining tool of steel cylinder low head.

At present, in the steel cylinder production process, form a steel cylinder integral body by upper cover and low head seal welding.And the process after the low head moulding needs port edging and constriction to close up (or claiming cissing), usually port edging and cissing divide two procedures, finish by cutting bed and two equipment of reducing bed respectively, such shortcoming is: 1. two procedures clamping low head workpiece at twice, be difficult to guarantee the perpendicularity of edging mouth and cissing, the percent defective height; 2. two equipment processing need more operation, producers; Production efficiency low, consuming time many, occupation of land side is many.

The purpose of this utility model provides a kind of perpendicularity that is easy to guarantee port cissing and edging for overcoming the deficiencies in the prior art part, the steel cylinder low head machining tool of enhancing productivity.

The purpose of this utility model is achieved by the following technical solution: the machining tool of steel cylinder low head, include lathe bed, column on the lathe bed, be fixed in the hydraulic jack at column top, the hold down gag that is connected with the hydraulic jack power end, the lowering device that can move up and down along column, location tire swelling device, main shaft, rotary actuator etc., special feature is a hydraulic jack, hold down gag, lowering device, location tire swelling device, main shaft is co-located on the same axis, on the position perpendicular to this axis corresponding location tire swelling device and main shaft on the lathe bed, one side is provided with edging hobboing cutter device, and offside is provided with cissing hobboing cutter device.

To drawings and Examples structure of the present utility model and advantage are described further below.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic diagram of edging processing;

Fig. 3 is the schematic diagram of cissing processing.

Referring to Fig. 1, Fig. 2 and Fig. 3, the lowering device 2 of present embodiment is used to carry low head workpiece 17 to be processed, just the low head workpiece 17 of one-step forming is put on the lowering device 2, the power end of hydraulic jack 12 presses down, by hold down gag 1 workpiece 17 is compressed, is positioned on the lowering device 2, the power end of hydraulic jack 12 continues descending, because lowering device 2 is socketed on column 9, therefore lowering device 2 moves down along column 9, until being unloaded, workpiece 17 covers on the location tire swelling device 3, and by tire swelling device 3 tensioners location, location.Main shaft 10 rotates under the drive of rotary actuator 11, and location tire swelling device 3 also drives workpiece 17 rotations thereupon.

The edging hobboing cutter device that is arranged in location tire swelling device 3 and main shaft 10 right sides includes neat mouthful of outer hobboing cutter 6, neat mouthful of interior hobboing cutter 7, and neat mouthful outer hobboing cutter 6 drives feeding by hydraulic jack 13, and hobboing cutter 7 drives feeding by hydraulic jack 14 in the neat mouth.As shown in Figure 2, workpiece 17 is during by location tire swelling device 3 driven rotary, in neat mouthful hobboing cutter 7 under hydraulic jack 14 drives by inwall clamping work pieces 17, neat mouthful outer hobboing cutter 6 drives the feeding cutting by hydraulic jack 13, the burr of workpiece 17 are removed, after edging was finished, neat mouthful of interior hobboing cutter 7 unclamped, neat mouthful outer hobboing cutter 6 returns.

Then, the cissing hobboing cutter device that is arranged in the left side starts, and cissing hobboing cutter device includes hobboing cutter 5 in the outer hobboing cutter 4 of reducing, the reducing, and the hydraulic jack 15,16 that drives feeding.As shown in Figure 3, hobboing cutter 5 is driven from inwall clamping work pieces 17 by hydraulic jack 16 in the reducing, and the outer hobboing cutter 4 of reducing drives feed by hydraulic jack 15 again, utilizes pressure that the port of workpiece 17 is dwindled, and after cissing was finished, hobboing cutter 5 unclamped in the reducing, outer hobboing cutter 4 returns of reducing.

Hydraulic jack 12 drives indenter device 1 rising and walks backhaul, and drives lowering device 2 along column 9 risings, unloads the low head workpiece 17 that machines to the blanking position, finishes the time processing process.

Such design has obvious advantage:

1, lowering device, location tire swelling device are finished cissing, neat to the workpiece clamped one time The limit. Effectively guaranteed the perpendicularity of low head cissing and edging;

2, realize on a machine tool the processing of edging, cissing, saved the labour, shortened and added Between man-hour;

3, occupied ground minimizing, production efficiency improve greatly.
